A King Cool refrigerator was a household appliance designed for keeping food cold, and made by the King Cool company. In 1957, a lead-lined King Cool refrigerator was installed in one of the houses in Doom Town, a fake town built in the Nevada desert for the purposes of nuclear testing. Escaping from Soviet troops, Indiana Jones heard the alarms announcing an upcoming nuclear weapon test, and headed into a house for shelter. With the countdown approaching zero, Jones dumped out the contents of the fridge, and took cover inside the King Cool appliance.
